From: Shiji Yang Date: Tue, 9 Jul 2024 16:16:36 +0000 (+0800) Subject: ramips: make SoC dtsi compatible with upstream mmc-mtk driver X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=338f40b3b4ff925985d3a2055ef09200778d1cd6;p=openwrt%2Fopenwrt.git ramips: make SoC dtsi compatible with upstream mmc-mtk driver Add all essential MTK SDHC properties to support the new mmc-mtk driver. Since this driver relies on power regulators, we also need to enable this feature for MT7620, just like MT762{1,8}.
